My lab works also on several projects to establish and refine proxy-calibrations. In collaboration with my post-doc Will Gray and my colleague Professor David W. Lea, I work on constraining the salinity and temperature effect on Mg/Ca of Globigerinoides ruber (white) and improving the application of Mg/Ca as SST proxy. To achieve these goal we using published and unpublished Mg/Ca data analyzed in samples from plankton tows and sediment traps (see salinity and sample map)
